Hello, so my right low beam isn't turning on and i checked the fuses and the connections...everything is okay, so i thought i needed a new bulb, but when i checked the high beams it works fine. So correct me if i am wrong but since it is the same bulb, doesn't that mean there is a connection that isn't going through or what?? im confused and now i can't drive at night unless i flash people...so any thoughts?

it's the bulb, the same bulb has the low and high beam but in diferent contacts, it's very commom to only burn "half" bulb, swap the right with the left bulb and you will see the problem swaping sides too!

hrm..i forgot to ask, how do i change the bulb, the shop did it for me last time, i know i have to remove the panel by lifting it straight up and there is a couple of wires and a connector, do i just pull that thing out or am i supposed to unscrew it out? thanks

I am having a very similar problem with both of my low beams. My fog lights work as do my high-beams. I do not believe it is the bulb, as both went out at the exact same time. I have replaced the fuses, and the light switch in the dash. I think that it is the high-beam lever on the steering column, but I am hesitant to pull it apart as of yet. I have access to a parts car (my best friend totaled his '94 E320 last week), so I have the part if that is the problem. I have looked at the wiring diagram and I can't think of any other place where the problem could exist.

Also under the plastic cover behind the fuses is the headlight relay. When it burns out it will stop suppling power to whatever lights it wants to. Multimeter the socket, no power replace the relay/check fuses of course. Suggest junk yard new they are about 200.

The headlights on my 88 260E would turn OFF when I switched from high beams to low beams. Very unsettling the first time it happened. If I fiddled with the beam change lever the lows would come on so I knew the problem was the steering column switch. I bought a new one and all ws well again. Not terribly easy to change that switch though. For one thing the big allen head screw holding the steering wheel on was VERY tight.

My260e, what harnesses did the dealer sell you? I know that the little harnesses that run from the headlamp bulb to the front lamp assembly connector on my car are shot. It seems that the terminals to the headlamp bulb oxidize, overheat, and then make poor contact. I've had to pop the hood and fiddle with the headlamp connector at times.
